Description

Technical Field

[0001] The utility model belongs to the technical field of oxygen supply therapy, in particular to a breathing mask. Background Art

[0002] Oxygen therapy is a medical treatment that increases the oxygen content in the blood by giving the patient extra oxygen to improve the patient's respiratory function and relieve tissue hypoxia. Mechanical ventilation is an effective treatment for patients with severe hypoxemia or who cannot maintain spontaneous breathing. Mechanical ventilation delivers oxygen to the patient's lungs and uses a ventilator to control breathing to maintain normal blood oxygen levels and carbon dioxide excretion. It should be noted that oxygen therapy requires determining the appropriate oxygen concentration and flow rate based on the patient's specific situation and cause of the disease. Too high an oxygen concentration may lead to oxygen poisoning, while too low an oxygen concentration may not be able to meet the patient's oxygen needs. In the process of oxygen therapy for patients, breathing masks are often required.
